This invention relates to improvements in columns, such as distilling columns, dephlegmating towers, scrubbing towers, absorption towers and similar towers.

In U. S. Patent No. 1,366,956, issued Febtaining a sequence of baille plates alternately of the plate and baiie ring type, said baile plates being downwardly inclined to prevent the accumulation of liquid. Curved vanes are provided between the plates and baiiie rings therebeneath, said vanes lying in a general direction substantially inclined to radial direction, for the purpose of imparting a circular and whirling motion to the ascendin vapors or gases wherebyeffectivc contact an interactionbetween the descending liquid and the ascending vapors'or gases are attained.

According to the present invention columns of this type are improved so as to give increased capacity with slightly less back pressure. The invention will be readily understood from the following description of a preferred embodiment which is illustrated in the accompanying drawings, in 4which-4 Figure 1 is anelevation, partly in section, of an improved column 5 and Figs. 2 and 3 are sectional details.

Referring to thedrawings, 10 is a column,

11 and l2 are ba'ie plates alternately of the plate and ring type. Itis preferred that the referably the plates 11 are approximately the same size as plates 12.'

Vanes 13 are provided between plates 11 and rings 12 for the purpose of imparting a whirling 'or circular ,motion to the vapors passing therebetween. Thesevanes are prefat 14. (Fig, 2.) It is preferred that the remainder ofthe van-es' 13 should be spaced somewhat inwardly4 from the inner periphery of the rings 12 as sho'wn at 15. (Fig. 3.)

The improved column may be provided with suitable inlets and outlets, for example, 16 may be a vapor inlet, 17 a vapor outlet, 18 a liquld inlet and 19 a liquid outlet. Although the present invention has been described in connectionr` with the details of a specific embodiment thereof, it is not inf my hand this 12th da of May, 1927.

the openings in the ring erably curved and lie in a general direction l substantially inclined to the radial direction.

The vanes preferably lie substantially completely below the plates 11 and do not substantially overlap the ring plates 12. The vanes 13 are preferably formed integrally with the plates 11 and the assemblage may be supported on the rings 12 by the slight overlap of a small number, for example, three or more, of the vanes on the rings 12 as shown
